ztree+json,渲染树形菜单

2021-11-24 14:00:15 浏览数 (1)

前面的话:zTree 是一个依靠 jQuery 实现的多功能 “树插件”。优异的性能、灵活的配置、多种功能的组合是 zTree 最大优点。专门适合项目开发,尤其是 树状菜单、树状数据。

ztree官方文档:http://www.treejs.cn/v3/api.php


现在写了一个小的demo,具体可以参考官方文档,从文档上拿来一串json数据,放在前端的代码里面,方便大家查看效果,以及方便后端返回的数据。

            $.fn.zTree.init($("#sys"), setting, nodes);

    </script>

</html>

在浏览器里面打开,效果如图所示:

把demo放在了github上面,有需要的可以自行下载;github:https://github.com/wangxiaoting666/ztree

现在如果是把数据放在json里面,通过ajax去请求,动态渲染出来。 这里的一切插件直接去前面给到的ztree的官方网站上去下载到本地,就可以直接引用了。 demo如下:

        //请求数据
        function initTree() {
            $.get("test.json", function(data) {
                console.log(JSON.stringify(data));
                zTreeObj = $.fn.zTree.init($("#zTree"), setting, data);
                zTreeObj.expandAll(true);
            });
        }
    </script>
</html>

test.json数据 自己动手,写一些模拟的json数据吧。
